When x = -3
Well that's easy put the three in place of the "X" and add or what ever it says
A mathematical expression in its' most simplistic form, merely assigns a value to a variable. Don't confuse an expression with an equation. An equation requires a solution. An expression cannot be "solved". It only allows you to determine the value of a variable. This is the expression in words "x is equal to 3" (X is the variable which is equal to the constant number 3) This is the expression in numbers "x=3" The expression in words "y is equal to 6" (Y is the variable which is equal to the constant number 6) The expression in numbers is "y=6" I hope you understand now.
It is rational.The square root of 9 is 3 and it is a rational number
10^3(8.75) would equal 10^26.25 which would equal: {| |- | 1.77828E+26 |}
I can see no rational expression below.
This is wrong

The answer is given below.
6 ÷ 10
When x = -3
If x = 3, then x + 10 would be 3 + 10, which is 13.
The math definition of a rational number is any number a/b so that both a and b are integers, except b ( the denominator) cannot be zero. So if you can manipulate the expressions to become this form, a/b, then it is the equavilent of a rational expression. Rational algebraic expressions are similar, except they contain variables. The same condition for the denominator must be true. The entire expression in the denominator cannot equal zero, but the variable might equal zero. Ex. a 1 / (x-1) .... x-1 cannot equal zero, which means that x cannot equal 1. Ex. b (1/3)/(1/4) can be simplified into 4/3 which is a rational number.
The answer would normally depend on the form of the expression: (-10)^3 or -10^3 but in this case they both equal -1000

An algebraic expression that is not equal (Such as 3=0) is called an inequality, and can be expressed as 3≠0.
0.3 is a rational number. The fact that it is expressed as a decimal does not mean it is not rational. As a ratio, it can be written as 3/10.
